Self Propel doesn't work! where does the cable attach from handle? How do u do it?

Re: Self Propel doesn't work! where does the cable attach...

If you haven't already gotten this fixed, simply remove the two screws on the bottom of the handle. Inside is the cable; please make sure to unplug your vaccum first.

Why won't hoover wind tunnel self-propel?

Hi there! The self-propelled feature is controlled by a belt. Check the belts on your Hoover Windtunnel by following these quick steps.

1. Recline the handle. Lay the cleaner fat and flip it over to expose nozzle base.
2. Remove the screws attaching the nozzle.
3. Check that the belts are not broken, stretched or damaged.

Replace the belts if they are damaged. Hope this helps!

Move the carpet height control switch to a higher position if the vacuum is difficult to push.

Just put handle on windtunnel u6401-9rm and the self propelled switch will not flip into self propel mode. is there an adjustment on the self propel part?

When installing the handle on this machine, you must be sure the on/off switch and the self propel button are both in the OFF position. The actual switch inside must also be OFF, and the metal fitting on the end of the power drive cable should be between the two lines molded into the plastic. After it is re-assembled, it is sometimes necessary to wiggle the handle up and down a bit to engage or disengage the drive button.

Hoover wind tunnel won't self propel

There are really two reasons why the self-propelled wouldn't work. It could either be the belts on the vacuum cleaner are stretched or broken. The belts on this model control both the self-propelled transmission, as well as the brush roller. Here's a video that shows you how to inspect the roller brush and belts to make sure that they are installed properly and working. Try this repair first, as this is the easier one to fix.

The other problem if the belts are installed properly that would cause the self-propelled wouldn't work would be the self-propelled actuator arm. There is a cable that starts at the handle of the vacuum, and runs all the way down to the floor head of the vacuum that controls the transmission. As you pull backwards on the handle of the vacuum, the cable pulls this actuator arm backwards, which then turns the wheels backwards, and when you push forward it turns the wheels forward.

The problem with the way it's designed however, is that if you pick up the vacuum cleaner by the handle of the machine rather then using the carrying handle on the back of the vacuum, it causes too much tension on the actuator arm, and will cause the cable to rip right out of the arm.

This is a VERY common problem on this model. To check and see if this part is broken on your vacuum, step on the handle release pedal so that the handle is in the vacuuming position, push the pedal a second time so the machine lays flat on the floor.

Now if you look right behind the height adjustment switch, and the rug / floor switch where the floor part meets the upright part, you should see a cable that connects into the actuator arm. Pull up and down on the handle and look for movement. Is the cable loose with only a nut attached to it, or is it resting in the actuator arm?

Here's a very helpful link that shows you exactly how to replace the actuator arm:

If this didn't help you, and the problem is still happening, please just use the add a comment form here on Fixya and let me know that you're still having problems. I'd be honored to go through and do some more advanced diagnosing with you.

Self propel unit broken

This is a farily common repair on this model. What ends up happening is that when someone picks up the vacuum cleaner2_bing.gif by the handle of the machine, which on this model also is the controller for the self-propelled transmission, it places too much strain on the actuator arm of the vacuum2_bing.gif cleaner.

You can do the best to try and not pick up the machine by the handle, but instead using the carrying handle on the back of the vacuum cleaner, this is distribute the weight much better, and even make the machine seem less heavy, and this will also prevent the actuator arm from breaking again in the future.

Now for fixing your vacuum, Please click the link below for an excellent tutorial on how to replace this part;

Hoover Self-Propelled WindTunnel U6436-900 cable problem

The flat belt should be changed if it has been longer than 9-12 months. Next I would remove the upper handle to inspect the top section of the control cable, sometimes it fray's and has a sponge feel (no positive control) to self propel. To set this adjustment, it is best to do withthe hood off of the lower section. I would also look at the cable jacket in the foot to make sure it is under the metal clamp. It must be under the clamp to work properly. To get it under the clamp loosen one hold down screw at the top and one in the back of the vacuum, remove clamp screws and put jacket into position and then secure all screws. Now set the adjustment, Install upper handle and set self propel to off. loosen cable from arm in foot with torx screw. manually move arm until the clutch is off both drive pads. This is a visual adjustment. then secure and reassemble vacuum.

Self Propelled does not work

if you look below the headlamp of your vac you will find a cable that attach's to a piece called the actuator arm. either this piece is likely broke or the cable itself. always work the power drive smoothly or things will break. also could be that the smooth belt is stretched and will cause the same problem. belts should be replaced every 4 months. good news is all parts above should be under $5. dont let anyone tell you that you need a power drive assy, that usually isnt the case. good luck!!!

Self propel will go foward, but will not reverse. Seems like handle is all the way extended.

There is a cable that connects to the handle and goes down to the powerdrive transmission. It is visible at the actuator arm on the drive if you look at the bottom of the handle where it pivots on the main housing. It will be on the right hand side, front corner of the handle bottom. You should be able to see the cable connected to the arm of the drive and will move back and forth with the top handle. Sometimes, they break at this connection. The cable may be frayed and broken, or the acuator arm may be broken where the cable connects.
This could also be a simple worn belt problem. The roller is always rotating in a direction that pulls the machine forward and if the belt is worn, the roller will turn sluggishly but still enough to pull forward, but the belt also drives the transmission and a worn belt will not have the capacity to overcome the forces involved to propel the machine backwards. Always change the belt(s) yearly.(on average)
